A new report claims Massachusetts Sen. Elizabeth Warren and her husband made thousands of dollars by buying and selling foreclosed homes.

According to National Review, Warren and her husband took in at least $240,500 by flipping houses between 1993 and 1998. And she allegedly did so before stitching together her political career by standing up for everyday Americans — particularly in the face of bigger fish trying to make money off the lower class.

Warren, a Democrat, has also campaigned for consumer protection and helped spearhead the creation of the U.S. Consumer Financial Protection Bureau. And she's talked about the economy and helping Americans improve their financial situations.

The National Review story claims Warren and her husband flipped at least five houses in Oklahoma City for profit, including a home built in 1924 that they sold for $115,000 more than they paid for it.

"I don't think it's right, but I don't really know much about it. … You flip houses to make a profit, so I can't really fault [Warren] much," the granddaughter of the previous owner of the home built in 1924 told National Review. "I think my grandmother made a mistake by selling it for so cheap. … She had worked hard all her life and was a self-made woman."

Warren has said she voted Republican before moving left in the mid-1990s.

Another report, meanwhile, claimed Warren was paid $90,000 to serve as a witness in a 2000 investor-state dispute settlement case prompted by the North American Free Trade Agreement. Warren and other Democrats have stood against President Barack Obama's recent trade moves as he brokers a deal for the U.S. to enter a trade agreement with Pacific-rim nations.

An attorney who worked on the 2000 case criticized Warren, saying she "did not appear to have any qualms about participating in this process that she now finds appalling."

Warren, who was voted into the Senate by defeating incumbent Scott Brown in the 2012 election, is also making a push for the government to regulate how car dealers provide auto loans to consumers.
